At 38, Irish designer Simone Rocha is already 12 years into a remarkable career in fashion—not only because her designs waft down runways, fill the closets of everyone from Rihanna to Billie Eilish, and populate flagships in New York, London, and Taipei, but also because each piece is so recognizably Rocha’s. She’s always true to her own aesthetic, which Tim Blanks, a fashion journalist and contributor to Rocha’s new, eponymous book, once deemed “Alice-not-quite-in-Wonderland.” Simone Rocha, a fashion book doubling as a memoir, comes out Tuesday, just weeks after the designer unveiled her new spring 2025 collection in London. To celebrate, the always-on-the-go Rocha details her travel routine.
